The DELAY command causes the execution of commands to be delayed by a user-defined time. This command
is similar to the *WAI common command, except that execution resumes after the specified number of
milliseconds, instead of waiting for the Operation-Complete flag to be set.
SYNTAX DIAGRAM
PARAMETERS An <nrf value> which represents the delay time, in milliseconds.
POINTS OF
INTEREST The Operation-Complete flag is held false until the delay period elapses, but the *OPC? query
will not execute until the delay period has elapsed.
This command is useful for creating delays which don't require a lot of program code and don't
tie up the GPIB during execution.
The delay time is approximate, with an error of about ±10%.
EXAMPLES "DELAY 500" -action: Further commands and queries are not executed until about 0.5 seconds
have elapsed from the time this command is executed.
"LAS:LDI 22;Delay 2000;LAS:LDI?"
LDX-3200 Series Precision Current Source waits for about 2.0 seconds before returning the
measured current.
Care should be taken to set the GPIB time-out appropriately for use with the Delay command.
